Genome-wide mapping of MAT2A-associsted regions in bovine blastocysts

Project description:Methionine adenosyltransferase (MAT), that catalyzes the synthesis of S-adenosylmethionine (SAM) from ATP and methionine, is involved in folate-mediated one-carbon metabolism (OCM) that is essential for preimplantation embryos in terms of both short-term periconceptional development and long-term phenotypic programming beyond the periconceptional period. SAM is the universal methyl donor for epigenetic methylation of DNA and histones. In the context of the long-term phenotypic programming by the modulation of OCM during periconceptional period, possible interactions between MAT2A and epigenetic status of specific genes during this period are of particular interest. MAT2A has been proposed to interact with many chromatin-related proteins and be recruited to their specific target genes to constitute gene-regulatory complexes. Thus, in the aim of addressing the possible interaction of MAT2A with specific genomic DNA regions in periconceptional period, we performed a ChIP-seq analysis using MAT2A antibody against bovine blastocysts.

High Glucose (HG) treated morula vs control glucose (CTL) treated morula

Project description:Early bovine cleavage (day 0 to 3) was treated with high glucose (5mM) or control glucose (0.2mM) then total day 3 embryos were cultured in control condition until day 5 when gene expression was assessed in developping morula by microarray 4 replicates of 10 morulae/rep was produced for high glucose and control treatment. According to a dye swap design, 4 arrays were used, one array for each comparison between HG and control, i.e replicate 1 from HG were compared to replicate 1 from CTL, rep 2 from HG were compared to rep 2 from CTL, rep 3 HG vs rep 3 CTL, rep 4 HG vs rep 4 CTL.

KDM6A improves the efficiency of nuclear transfer reprogramming in bovine

Project description:As a histone hallmark for transcription repression, Histone H3 lysine 27 trimethylation (H3K27me3) plays important roles in mammalian embryo development and induced pluripotent stem cells (iPSCs) generation. However, the expression profile and roles of H3K27me3 in bovine somatic cell nuclear transfer (SCNT) reprogramming remain poorly understood. In this study, we find SCNT embryos exhibit global hypermethylation of H3K27me3 from two-cell to eight-cell stage and its removal by ectopically expressed H3K27me3 demethylase-KDM6A could greatly improves SCNT efficiency. To illuminate the mechanism of improving SCNT reprogramming efficiency of KDM6A overexpression, we performed RNA sequencing of transcripts in SCNT morula with or without KDM6A overexpression. RNA-seq reveal that KDM6A overexpression could enhance transcription of genes mainly involved cell adhesion and cellular metabolism process, as well as X-linked genes. We first provides the transcriptome data of bovine SCNT morula with or without KDM6A overexpression. Meanwhile, we compared the differences of transcriptome between SCNT eight-cell embryos and morula. Our study provide a more promising approach to improving the efficiency of SCNT reprogramming and contribute to understanding the mechanism of first cell fate determine during embryo development in bovine.
